before you connect the DC power source. Before you
make any wiring adjustments, always verify that all power
sources are not live.
Connecting the DC Power Source

terminals at the Rig Monitor housing. Use the other end to connect a 12
VDC battery.

or disconnecting it from the 12 VDC battery.
1. Turn off, unplug, or disconnect all incoming power to the Rig Monitor.
2. Open the housing door, then place the power switch in the OFF
position.

4. Connect the black battery clamp to the (-) terminal of the 12 VDC
battery.

Rig Monitor. The common alarm 1 terminals are factory wired and are not
available for field use.
NOTE: The alarm terminal strip includes terminals for channel alarms
and common alarms. Channel alarms are activated by one
particular channel. Common alarms are activated by either of the
two channels.The example used in this procedure describes
connecting an external alarm device to one of the channel alarm
terminals: the channel 1, alarm 1 terminals.
1. Disconnect the battery clamps from the + and - terminals of the 12 VDC
battery.
2. Open the housing door, then place the power switch in the OFF
position. Locate the alarm terminal strip (see Figure 1).
